Hi, We use the assembler for PIC microcontrollers (ASM4PICS) with the Eblocks boards. I recently tried using a Windows 10 laptop. Software loaded and ran OK but the USB cable could not be found. We will be going over to Windows 10 in the next year or so. We therefore need a solution as we wish to co...

By the way the LCD display seems to work fine.

Hi, It does seem to be some sort of timing issue. The individual segment displays are not fully off when the data is applied to port B resulting in a residual output to the un-selected digits. This doesn't happen with the stand-alone LED display but this doesn't have the additional LEDs etc which th...

I don't know if this helps you track down the problem. Tutorial 26 works fine with the E blocks LED 7 segment module. i.e. two digits counting up in decimal. When using the combo board both digits show the same information which changes with the count. The multiplexing of the display is not working ...

Hi, The ANSEL register is cleared as part of the tutorial 25. The problem seems to be that Port A is not putting power onto the anodes of the display chips. I'm pretty sure that the combo board will not work "fully" with all tutorials without some additional modifications to the tutorial programmes....

We are using the Eblocks multiprogrammer board in conjunction with the Eblocks EB083 combo board. We are using assembly for PIC micros software and tutorials. When we get onto the tutorials which use the 7 segment displays (Section 2 of the tutorials) these do not work correctly on the combo board. ...

Back in May 2012 I finally got the v2 development board running with PPP v3 although there were still some issues regarding linking the various bits of software. I've now returned to this problem and although the v2 development board is auto-detected (I'm using the LPT interface) when I try and auto...

Hello David, I can confirm that Vlab won't open directly from ASM4PIC but will open and run via the ICON in IDE. I've also tried the following: RUN ASM4PIC Opened tutorial 2.1 (Tuta2.asm) Opened full listing/IDE (get unknown error if try to assemble) Saved file as To2.mxa file into my file area on t...

I don't think that I can open Vlab directly from Assembly for PIC micros but if I open the IDE Vlab runs OK from there.

I'm out tomorrow but I'll check on Thursday.

I haven't tried the 64bit fixes but I suspect that I'll need to get IT involved because of the privelages required.

Thanks,

Keith

Hello, As I work at a College only the IT department have admin rights to install programmes etc. As a result it can take some time to get programmes re-installed etc. The programme is installed locally on the PCs and I followed the path for the assembler. The MPASMWIN.exe programme seems to run OK ...

Hello David, Sorry for the delay, half term. I've pasted a screen shot but the they are missing the early parts of the path. Assembler C:\ Program files \ Matrix Multimedia \ ASM4PICsV4 \ MPASM Suite \ MPASMWIN.EXE / ..... Programmer C:\ Program files \ Matrix Multimedia ..... PICconfigure C:\ Progr...

Hi David,

Please find word file with screenshots. The second shot is seen after closing the error window.

Thanks,

Hi, I have a version 2 development board with a PIC16F84A connected to the LPT port of a PC running Windows XP service pack 3. I am running PPP v3 and ASM4PICsV4 If I launch PPPv3 I can autodetect the version 2 board under options and autodetect the 16F84A. Still in PPPv3 I can navigate to a .HEX fi...
